Using both annotation and XML config on one instance bean

I'm creating a service using annotation:

@Service
@Repository
public class UserServiceImpl implements UserService {
  private String defaultPassword;

  @Autowired
  private UserRepository userRepository;

  // ...

  @Override
  public void setDefaultPassword(String defaultPassword) {
     this.defaultPassword = defaultPassword;
  }

  @Override
  public String getDefaultPassword() {
     return defaultPassword;
  }
}

I want to configure defaultPassword value using Spring XML configuration not via annotation, so I added the following in XML definition:

<bean id="userServiceImpl" class="com.test.service.UserServiceImpl">
   <property name="defaultPassword" value="youmustchangethis" />
</bean>

Then, I write test like:

public class UserServiceImplTest extends AbstractServiceImplTest {

  @Autowired
  private UserService userService;

  // ...
}

I've matched the bean name in annotation and XML declaration (using bean id). My question is will userService variable in UserServiceImplTest always injected by the same singleton bean that configured in both XML and annotation? I've searched the documentation but didn't find explanation for 'hybrid' approach like this.

In this case bean defined in xml file will overwrite bean generated from annotation. That is because spring names annotation beans based on the class name with the first letter changed into lowercase. Unless you give it an explit name. There cannot exist two beans of the same name so xml definition overrides the annotation one.

You end up with one singleton called userServiceImpl here.
